The essential American soul is hard, isolate, stoic, and a killer. It has never yet melted. — D.H. Lawrence

Iraqis are permitted to own fully-automatic AK-47s in US-occupied Iraq. But the BATF won’t let you own an Akins Accelerator, a gizmo which attaches to the trigger mechanism of a Ruger 10/22 to achieve full-auto function.

Nothing attaches to the trigger mechanism and it does not achieve full auto function because the trigger is functioned once for each and every shot. The entire barrel/receiver/trigger group reciprocates backwards under recoil removing the trigger completely from the finger and compressing a spring which then forces the barrel/receiver/trigger group back forward again.
